How to transform Firefox into a Text-to-Speech application

Although there is no built-in text-to-speech option, you can use plug-ins to enable the Firefox browser to read the content of a web page out loud.


      Text-to-Speech for Firefox offers the option of having text read out loud in a Firefox browser. The user simply points out the content, right clicks, then chooses the little green circle on the written content to begin the reading function.

      Most people prefer to listen to audio than read written content. In addition, there are hundreds of millions of people globally who face dyslexia and other learning difficulties. For them, listening to a website’s written content is much easier than reading it. If Firefox is your preferred browser and you want to hear the contents of a website, then you have come to the right place.

      Developers have built text-to-speech add-ons for Firefox that are free to download and install. Some of these add-ons support several languages, ​​and even allow you to convert written content to an audiobook or an MP3 file.
